A former Mega Decks customer buys a new house and needs a new deck. Can designer Andy and the build crew live up to the client's heightened expectations and deliver a second mega deck that beats the first? Jason leads a $225,000 build that includes a complicated roof on existing architecture, a soaring tongue-and-groove ceiling with a skylight, a floor-to-ceiling fireplace with an articulated mounted TV, a state-of-the-art grilling station, four seating areas, moveable glass walls and a 14-foot fire rail with stone masonry.
